As rumble said, "Install an oil pressure gauge". Cheap insurance & you don't have to rely on an idiot light that usually comes on "way" too late.

I put a T on it and run gauge and light and if I could I’d hook up a big wet mitt that would come out of dash and slap me up side the head if it lost oil pressure. Sometimes asleep at the switch
